I have solved this thread because as @Junkhacker stated, this is fixed in the dev builds as I am not using gzip compression on the page at all any more. If you are worried about the display, please update to Dev.

This is specific to using ob_gzhandler which was present, I believe, in 1.0.0 up to 1.2.0, and I typically only saw this on systems hosted by Ubuntu or Debian. It isn’t doing any harm, but it doesn’t look right either.
